termediate transversely disposed portion of the U-shaped machine frame is supported. The upper ends of the bolts 15 and 17 are connected by means of the longitudinally disposed plate 21.

Upon the forward ends of the longitudinal portions of the main frame 5, the bell crank levers 22 are fulcrumed. A rod '23 connects the longitudinally disposed arm of each of these levers with the draft bars 11. To the other ends of the bell crank levers, the oppositely extending obliquely disposed rods 2% are connected, the rear ends of said latter rods being pivotally connected to the operating levers 25. These levers at their lower ends are loosely mounted upon a rod 26, which connects the rearwardly extending arms 28 formed upon a bar 27 which is longitudinally arranged upon the central portion of the axle bar 7 and is bolted or otherwise suitably fixed thereto. From this construction, it will be apparent that when the operator pulls either of the levers 25 rearwardly the draft bars 11 carrying the tongue to which the animals are attached will be swung transversely to one side or the other of the center of the machine. Thus the machine may be properly steered or directed by the operator to avoid injury to the plants in the operation thereof and to insure a thorough cutting of the weeds close to the plant row.

Upon the axle bar 7 and adjacent to each end thereof, a perpendicular forked standard 29 is adjustably secured by means of suitable clips indicated at 30, which embrace the axle bar and have their ends disposed through openings in the standards. It will be appreciated that by simply loosening the clips, the standards may be shifted longitudinally upon the axle bar. The purpose of this adjustment will become readily apparent as the description proceeds. In the upper ends of the spaced arms of the standards 29, the ends of a transverse rod or shaft 31 are j ournaled and upon said rod bet-ween the arms of the standards an oscillatory member 32 is loosely mounted. The standards 29 also extend below the vehicle axle and to said lower ends thereof the members 33, of similar form to the members 32, are pivotally connected. These members 32 and 33 extend rearwardly of the shaf 31, and are each bifurcated to provide spaced parallel arms 3% and 35 respectively. Transverse bolts 36 and 37 connect the arms of the also be observed that by providing these projections or extensions, upon the upper ends of the bars 39, sockets 41 are produced between said projections and the arms of the members 32. The ends of the members 32 which are mounted upon the rod or shaft 31 are provided with arcuate notches or recesses 42 with the rear end walls of which the pins 4&3 arranged in openings in said shaft are adapted to engage, so that the simultaneous movement of the members 32 will be effected when the shaft 31 is rotated in the bearing standards. Normally, when the disks are in their operative positions, the pins 43 are disposed in the lower ends of the slot-s t2 so that the members 32 may rock upon the shaft 31 independently thereof, the rear ends of said members moving vertically when the disks encounter and pass over obstructions in the path of the machine, such independent movement of the members 32 being limited by the upper walls of the slots 42 engaging the pins 43 fixed in the shaft 31. When it is desired to lift the disks, the operator rotates the shaft 31 in the proper direction through the medium of the lever 59 to engage the pins &3 with the lower end walls of the slots 42, and thus swing the rear ends of the members 32 upwardly, thereby also elevating the parts connected to said members.

The weeding disks shown at 44 are provided with scalloped or notched edges and an arbor or journal stud a5 is centrally fixed to each of said disks. These journal studs are mounted in suitable bearings secured rigidly upon the longitudinally projecting ends 427 of the suppoifing rods 47. These bearings in which the journal studs are mounted to rotate may be of any approved construction. The bearing sleeves for the journal studs are preferably adjustably se cured upon the longitudinal portions 47 of the rods 47 by means of set screws indicated at 46 whereby they. may be rotated to dis pose the weeding disks at any desired inclination.

Upon the bearings 46, the downwardly and inwardly inclined arms 48 are mounted, said arms being provided with slots through which the bolts &8 fixed in the bearings extend. These bolts are provided upon their upper ends with suitable clamping nuts whereby the bars 48 may be securely clamped in their adjusted positions. The lower ends of these bars are longitudinally and forwardly extended and upon the same the guards or shields generally indicated by the numeral 19 are mounted. These guards include the longitudinally disposed plates 50 and the curved plates 51., said latter plates extending in substantially con centric relation to the weeding disks 14 and contiguous to the peripheries thereof. The plates 50 carry spaced bolts 51 to be re groups of Weeding and cultivating disks have independent vertical movement, they will readily pass over low obstructions which may be encountered upon either side of the plant row, thus obviating liability of breakage of the parts, and also increasing the operating eli ieiency of too machine to a maximum degree. The machine is highly efficient and reliable in practical use and may be operated with the expenditure of a minimum amount of labor on the part of the operator. Owing to the simple construction of the various elements employed in the machine, it will be obvious that the same can be manufactured at comparatively small cost, and that it is also extremely strong and durable in use.

l Vhile l have shown and described the preferred construction and arrangementof the various elements, it will be understood that the invention is susceptible of consi lerable modification without departing from the essential features or sacrificing any of the advantages thereof.

Having thus described the invention, what is claimed is:

1. in a machine of the character described, a rock shaft, arms loosely mounted upon said rock shaft, weeding disks to travel upon opposite sides of a plant row, means for mounting the disks upon said anus, and means carried by the shaft to engage said arms when the shaft is rocked to elevate the disks and support the same in an inoperative position.

2. In a machine of the character described, a rock siaft, arms loosely mounted upon said rock shaft, hanger bars suspended from said arms, spaced weeding disks to travel upon opposite sides of a plant row, means for removably mounting said disks upon the hanger bars, said arms having limited oscillatory movement upon the rock shaft whereby the disks may move independently of each other in a vertical plane, and means carried by the shaft to engage said arms and elevate the disks when the shaft is rocked and support the same in an inoperative position,

3/ in a machine of the character described, a rock shaft, bearings therefor, arms loosely mounted upon the rock. shaft, and having limited oscillatory movement thereon, similar arms pivotally connected at one of their ends to the shaft bearings, members connecting the arms at opposite ends of the shafts, spaced weeding disks, means for detachably mounting said disks upon the connecting members, and means "iel by the rock shaft to engage the thereon whereby the disks are elevated when the shaft is rocked and supported in an inoperative position.
